Expressions for the efficiency factors for radiation pressure for infinite circular cylinders are presented. Planck mean cross sections for radiative pressure have been computed for static oriented cylindrical grains composed of graphite, pure and dirty iron, ice, silicates (obsidian and basalt) and silicon carbide. The cylindrical grains radii range from 0.001 to 1 μm and the effective temperatures used are 3300, 5770, 15500 and 40000K. The dependence of these mean cross sections from temperature, grain size and the direction of the incident radiation is discussed. It is found that for metallic particles Planck mean cross sections for radiation pressure depend on the state of polarization of the incident radiation.
